Hi All,<br>
<br>
I've been doing some research into getting the Blender Game Engine
working in one of our domes <br>
<ul>

</li>
</ul>
Our domes use a cylindrical (or spherical....we just chop the top
and bottom off) panoramic projection that is ideally 8000x1100 but
anything above 6400x950 looks ok. We do all of the image slicing,
warping and edge blending in a custom app but need a way to get the
image out of the BGE and into our app. In unity we use 5 cameras
oriented around the y axis each with a fisheye effect to approximate
a cylindrical camera - we then use <a
href="http://syphon.v002.info/">syphon</a> under osx and <a
href="http://spout.zeal.co/">spout</a> under windows to output
these camera textures to our warping and edge blending app. Where
looking to do a research project with Loughborough University and
where we build an immersive training scenario in the dome and we're
after some help advice with this. <br>
<br>
As Syphon and Spout are both open source and widely used adding in
support for them would mean not only support for our (and others)
domes but also a wide range of other tool and uses like VJing,
museum installations etc and is something others have already been
asking for<br>

In this regards to getting syphon and/or spout added into the BGE we
were wondering<br>
<ol>
<li>Where in the codebase should I start looking to share the
render texture produced by the spherical dome render via syphon
and/or spout?</li>
<li>Would anyone (preferably one of the BGE module owners) be able
to provide timely support for this project for a small
consulting fee?<br>
</li>
<li>Would anyone be available to do this work and do you have a
ball park figure for what it would cost?</li>
<li>Does anyone have any feelings about what the performance
differences might be for a large (100,000+ vertex) textured
model between the spherical panoramic renderer and the approach
we have done with unity which is just 5 normal renders oriented?<br>
</li>
